Daily Punch 9-4-15 On Target metamagic feat for Pathfinder

I was reading a Pathfinder Tales novel, and one character summoned creatures on another. I’d like to make that happen in my games.

On Target(Metamagic)

When you create life or unlife, you can cast it on a a target.

Benefit: When you cast a conjuration or necromancy spell that creates or animates any number of creatures under the effect of this metamagic, you can make a ranged touch attack an a target in range for each creature created at a target within the range of the spell. If you hit the target with this attack, the creature is created on the target either grappling it or doing melee attack damage on the target as if it hit. The target may also make any attacks it would normally get its on its turn.

Level Increase: +1 (an On the Target spell uses up a spell slot one level higher than the spell’s actual level.)
